In a recent workshop the City of Portland, Oregon sponsored for its Willamette River Central Reach Plan , planners asked for habitat enhancement “projects that would have larger bang for the buck”. . . “projects that would have a multiplier effect in terms of watershed health.” Mycofiltration—the use of mycorrhizal mushrooms and their mycelia to filter pollutants would rank high on both of these criteria.

Mycofiltration will reduce harmful pollutants commonly found in urban stormwater runoff, such as heavy metals and polycyclic aromatic hydrocarbons, or PAHs. It also eliminates E-coli and other bacteria from pet wastes and waterfowl. Because adding mushroom spores to remediation sites is very inexpensive and low-impact, it has the potential to be a sustainable option well into the future.

In most places, stormwater runoff goes directly into streams, rivers and oceans and recycles through the watershed carrying the pollutants with it. And that it is a big problem for salmon and wildlife survival. Mycofiltration should be added as a treatment to enhance the activity of existing stormwater management biofiltration cells such as the rain gardens, bioswales and green streets that are plentiful in Portland. By adding Garden Giant (Stropharia rugosoannulata) mycelium to the soil mix, harmful substances that come from heavily trafficked roads such as I-5, I-84 and the motor vehicle bridges in the Central Reach: Broadway, Steel, Burnside, Morrison, Hawthorne, Markham, Ross Island can be transformed into carbohydrates and nutrients — which are actually useful to surrounding soil and plants cheap cialis overnight delivery.

By adding mycofilters to biofiltration cells installed in places where people walk their dogs such as South Waterfront, Riverplace, Waterfront Park, Eastbank Esplanade, etc., E-coli and other bacteria from pet wastes that were not properly disposed of can become a nutrient rather than a pollutant. Having these mushrooms in the mix can actually help the native plants we are planting in streambank restoration and biofiltration cell facilities grow more robustly. Instead of dealing with pollutants, their roots are getting more nutrients.

Paul Stamets TED Talk 2008

I was fortunate enough to meet inspirational mushroom guru, Paul Stamets (here he is giving a TED talk) when he was first starting his farm near Olympia, WA in the 1980s. He had just wowed the Washington Department of Ecology with the use of mushrooms to clean up the E-Coli and fecal coliform problem caused by his farm animals. In a single year he had achieved a 99% reduction in pollutants despite doubling the number of animals on the farm.

Since that time, I have gone on to found my business PlanGreen around using ecosystem services to deal with urban stormwater and other environmental problems/opportunities. I believe, as Stamets does, that the Earth has its own immune system and that we need to learn to better work with that immune system. Although I have been excited about the efforts that Portland and other communities throughout the nation are making in biofiltration—using plants and soil to filter stormwater–I have long wondered why we were not utilizing mushrooms as well.

That sounds like a challenge that Portland area jurisdictions would relish. So PlanGreen is seeking to broker partnerships between Fungi Perfecti and receptive jurisdictions. Beyond treatment design and operating parameters, some of the issues to be resolved by those partnerships might be[i]:

Whether or not the mushrooms grown on decomposing toxic wastes are safe to eat.

To what degree of decomposition by mycelium of toxic soils makes the soils safe for food crops [including food for wildlife]

How economically practical will it be to remove mushrooms that have hyper-accumulated heavy metals. . .? Which species are best for hyper accumulating specific metals?

How to finance/design composting centers around population centers near pollution threats.

However, whether or not our cities, ports and other transportation agencies can qualify for the robust monitoring needed for the Fungi Perfecti research, we have enough anecdotal evidence (and PlanGreen and its partners have enough knowledge and materials) to get to the starting gate right now. As Stamets says in his book, Mycelium Running, “Now is the time to ensure the future of our planet and our species by partnering, or running, with mycelium.”

Environmental Workshop Comp Plan Update at the Native American Center, Portland State University

I went to the session the Portland Bureau of Planning and Sustainability had for the environmental community last night (April 3, 2013) on the current Working Draft of the new Comprehensive Plan. This session was held at the Native American Center on the Portland State University campus at the behest of two members of the Watershed and Environmental Health Professional Expert Group (PEG): Judy Bluehorse Skelton and Claire Carder. Judy gave a tour of the student-planted and maintained green roof atop the Center and someone else led one on the other green infrastructure on the campus.

At the session on “Healthy Economy, Healthy Environment”, I came to the conclusion that more of us who care about the environment need to be

praising manufacturers, like Toyota, who are willing to change their ways to restore the environment at their facility along the river (Please see my blog on Toyota.);

pushing the City to recruit more companies like Toyota and giving them suggestions from our own reading and research;

exposing industrialists in North Portland who are unwilling to work towards creating a healthy environment along with the jobs they tout;

asking lots of questions about proposed tax breaks for brownfield redevelopment and coming up with acceptable solutions.

supporting North Portland residents who are stewarding and restoring parks such as Pier Park that can become part of a wildlife connectivity corridor if linked to other natural areas.

I sent planners links to two recent articles by Richard Florida and Neal Peirce exploring “The Uselessness of Tax Incentives for Economic Development”. Both were based on a New York Times in-depth series on the topic. I already got a response from planner Steve Kountz distinguishing tax breaks for land from the tax breaks for business that the NYT series was largely about. I hope that he will put that response below in the comments.

Otherwise, we will see the continued erosion of what greenspace is left at the confluence of TWO great rivers–the Columbia and the Willamette–an area that is critically important to wildlife. Already, planners propose to take at least a portion of 800 acres of golf courses and most of West Hayden Island into industrial land. Many of us said we preferred that the City push the redevelopment of vacant brownfields first, but the difficulty Steve pointed out was cost. He encouraged us to read the City’s Brownfield Assessment report, but it seems the solutions boil down to tax incentives. Most of the group were wary about those as well.

Other solutions for wildlife that were discussed were green or ecoroofs atop factories and other facilities and bioswales along parking lots and roads. In its North Reach River Plan, the City has proposed the Willamette Greenway Plan be extended through the industrial corridor, but industry pushed back (see Toyota link above).

Please use this link to send the City your own comments. They are due by May 1,2013 but don’t delay until then. Do it today!
